Morphology

mammary + gland

The meaning 'milk-secreting organ in female mammals' is directly and compositionally derived from 'mammary' (relating to breasts/milk production) + 'gland' (an organ that secretes fluids). This straightforward noun–noun combination follows regular English formation and has clear parallels in other languages, so a B1 learner who knows both constituents would understand the MWE.

Etymology

The term mammary gland begins with mammary, from an old word 'mamma' meaning 'breast', and the part gland, a small organ that makes a liquid. It is the body part in female mammals that 'makes milk' and feeds their babies, so the name simply tells what it does.
